Specification of Letters Patent.

an" n nnnnann, or cnrcnolo, ntnrnor's- Application filed t me so, 1921. serial in. mm.

, Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Ribbon-linking Attachments for Typewriters, of which the follow 'ing isa specification.

The invention relates to ribbon inking attachment for typewriters.

One of the objects of the invention is to improve ribbon inking attachments for-typewriters. x

Another object is to provide a device that may conveniently be secured in place on a typewriter and as quickly and easily re moved.

Another object is the provision of an improved ink distributing device.

Another object is to provide an improved and more convenient manner'ot supplying ink to the ink device without removing the device. 7

Another object is to provide an inking device which will not feed ink to the ribbon when the ribbon is not being moved. I

Another object is the provision of an improved and convenient means for changing the character of ink of the ing device to suit the'ribbon without removing the entire device, from the writer.

Another object is to conveniently and temporarily stop the a Lag operation of the attachment without removing it from the typewriter. 7

Another object is to provide an t ng device by means of which a two-color ribbon may be inked at one time. I

Another 0bect is to provide'anautomatic device which continues to operate so long as the ribbon is fed through the typewriter during its ordinary use and which will, not impose noticeable resistance to the normal-operation of the machine.

@ther, further and more specific objects of the invention will becomeireadily apparent, to persons skilled in the art, from-5a consideration of the tollog description, when takeniin conjunction with th'edrawin%, wherein':---=

Fig. 6 is a detail. Fig. 7 is'a View similar to Fig. 5 showing two elements serving as fountains for two diiierent colored inks. i

Fig. 8 is an elevation of a double, ink distributing roller, or wheelffoi two difie'rent colored inks.

In all the views the same reference characters are employed to indicate similar parts.

line2-2 of I The device consists of a rectangular tube 10 provided with angularly extending arms 11 and 12. Pivoted in the outer ends of the arms is a distributing roller 13, having.

held in place by a removable screw 17 which passes through the arm 12 andis threaded inthe arm 11.

An arm 18 is pivoted to the rectangular tube 10, as at 19), and carries on its outer free end aroller 20, pivoted thereto by a screw 21 and held in contact with the distributing roller 13 by a spring 22. Between the pressure roller and the distributing roller the ribbon 16 is contained. 23shows one of the spools of the ordinary typewriter upon which the ribbon is wound.

. A rectangular fountain tube 25 slides freely in the rectangular tube 10 and carries an'ink-absorbing felt strip 26. The tube 25 is closed at its rear end, as at 27, and carries a rearwardly projecting stem 28 which is screw threaded on its outer end, as at 29,'for .a er mob 30. The fountain tube 25 has its upper wall slotted, as at 31, within which tointroduceink for saturating the felt strip 26. The tube 10 is provided in its upper Ml V i f tube is connected to a plate 418, as at 4L9,

which ink may be introduced into the slot for contact with the strip 26. k

A spring holding tube 33 is provided on its inner end with a head 34: that bears against the rear end of the tube 25. It has an enlargedend 35' which projects on theoutside of the tube 10. Around the tube 33 is wound i an open, helical compression spring 36 which lid 3 wall 37 of the tube 10. The spring 36 yieldfelt,- strip26-in contact with has one of its ends bearing against the head 3% and the other end bearing against the end ingly holds the front end of the ink feeding the ink distributing roller 13.

Tube 10 is axially slotted in one of its side walls, as at 38, and tube 25 bears an outwardly projecting pin 39 that moves in the slot 38 when the tube' 25 is axially moved by contact with the handle or knob 30. A

\ that both black and red ink, or other dillerent colored inks, may be fed to a two-color ribbon, and F ig. 8 shows a double ink 'distributing roller, consisting of the rollers 13 y and 13", separated or in one, adapted to dis- I it tribute ink of different rcolorsto a ribbon bearingcorresponding colors;

'When a single tube 25: is used and it is desired to change the character or the ink, it is only necessary to removethe screw 17 and take away the distributing roller 13,

whereupon the tube 25 may be taken from the tube matter the knob 30 has been unscrewed, so as to permit the stem 28 to pass freely through thetube 10 and the tube 33 contained therein, whereupon another tube 25, bearing a difierent character of ink, may

be substituted and"a diflerent distributing roller 13 may be inserted inthe ,place of the roller taken from the device,so that to change ink to suit the ribbon it is only nec- 50.

essary to change'the tube 25 and the roller '13 without removing'thex ti device from" the machine. e

A cover plate 413 is pivotedfasat 4A, to the tube 10 and normally overlies and covers the perforations 32 to prevent entrance of dust to the felt distributing strip 26.

425 represents a part of theframe'of a typewriter to which the device as a whole may" attachably be connected by means of the thumb screws 46 and 417. 'lhe outer and the plate carries strips'52 and 53 hav-' ing, on one ,end flangesj50 and 51, and on the other end'screws; 4:6 and'lfi. When it is desired to [remove the device from: the

. of typewriters may argest typewriterit is only necessary to loosen the screws 46 and t7 and to remove the ribbon 16 from between the pressure roller 20 and the distributing roller 13.

When the ribbon is moved in the ordlnary use of the typewriter, the ink distributing roller 13 is thereby rotated because the roller 20 yieldingly holds the ribbon in contact therewith and the thin film of ink that has been deposited upon the roller 13 from theinking strip-26 is taken up and absorbed by the ribbon. deposited upon the roller 13 can be absorbed Not any more ink than is by the ribbon and therefore when the ribbon 16 is standingstill, it is not supersatu rated as it'would be it it were directly in contact with the ink 'laden strip 26.

The attaching mwns for diflerent types style of the machine. v

Fig. 7 shows in a single structure two fountain tubes in which the ink feeding strip 26 'may be shorter than strip 26 so that the latter may be inked through slots 31 without removing the structure from tube 10.

The ink distributing roller 13 may be made in two separate parts or separated'by a circumferential groove and made in a single piece.

While 1 have herein shown a single embe modified to suit the bodiment of my invention for the purpose 01. clear disclosure, it will be manifest to persons skilled in the art, that many changes may be made in the general configuration and disposition ofthe parts within the scope of the appended claims.
